Embodiments of the present invention provide a method and system for controlling access to a non-SIP service, and a service registration center. In order to make the technical solutions of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1 , which is a flow chart of an embodiment of a method for controlling access to a non-SIP service according to the present invention. The non-SIP service in this embodiment is a network game service.

The specific process of accessing the non-SIP service includes:

Before accessing the non-SIP service, the service terminal will use the public address (AOR, Address of Record) of the non-SIP service, the actual access address such as Uniform Resource Locator (URL) address, interface address (socket) address, and non-SIP service. The corresponding QoS information is registered to the service registration center, and then the service registration center binds the AOR of the non-SIP service, the actual access address, and the corresponding QoS information. Therefore, the service registry records service characteristic information of various non-SIP services, including AOR, actual access address, and corresponding QoS information.

In this embodiment, the service terminal registers the network with the game AOR, network_game@huawei.com, the actual access address http://www.huawei.com/network_game, and the corresponding QoS information to the service registration center. An example of the registered QoS information is as follows:

<service name="starcraft" address^" http://www.huawei.com/starcraft " > <Parameter name="bandwidth" mode="equal" unit="Mbps"

needTransfer="TRUE">

</Parameter>

<Parameter name="responsetime" mode="equal" unit="ms"

needTransfer="FALSE" >

</Parameter>

</service> </AppQoS>

The element service in the above XML file represents the actual service, and its attribute name indicates the name of the service. The attribute address indicates the address where the service is located (this attribute is optional in the service request description), and the attribute Parameter is used to describe the service. The QoS parameter information, the attribute mode indicates the mode of the service, and is used to describe the QoS guarantee that the application server can provide. The equal value indicates that the QoS value provided by the application server is equal to the value corresponding to the sub-element value.

Step 101: The service terminal sends a SIP request to the P-CSCF of the IMS, where the SIP request carries an AOR of the non-SIP service;

The SIP request may also carry QoS information required by the non-SIP service, and the SIP request example is as follows:

INVITE sip: network_game@huawei.com SIP/2.0

To: sip: network_game@huawei.com

From: sip: virtual_trip@beijing.com; tag=werwe334s

<Parameter name="bandwidth" mode="more" unit="Mbps"

needTransfer="TRUE">

</Parameter>

<Parameter name="responsetime" mode="less" unit="ms"

needTransfer="FALSE" >

</service>

</AppQoS>

Step 102: The P-CSCF forwards the SIP request to the home calling party S-CSCF of the service terminal.

Step 103: The home calling S-CSCF forwards the SIP request to the corresponding application S-CSCF according to the AOR carried in the SIP request.

Step 104: Apply the S-CSCF to forward the SIP request to the service registration center according to an (iFC, Initial Filter Criteria) rule;

The SIP request may also be forwarded directly by the home calling S-CSCF to the service registry. Step 105: The service registration center obtains QoS information and an actual access address corresponding to the non-SIP service according to the AOR in the SIP request.

If the session initiation protocol request only carries the AOR of the non-SIP service, the specific process for the service registration center to obtain the QoS information and the actual access address corresponding to the non-SIP service according to the AOR in the SIP request includes the following steps:

Step A: The IMS obtains the subscription service quality information of the non-SIP service from the home subscription server; the home subscription server stores the subscription service quality information of the various non-SIP services.

Step B: Determine, according to the AOR in the SIP request and the subscription service quality information of the non-SIP service, whether there is service characteristic information that satisfies the condition in the IMS, and if yes, obtain the actual access in the service feature information that satisfies the condition Address and corresponding quality of service information.

The service registry records the AOR of the non-SIP service, the actual access address, and the corresponding QoS information. Therefore, according to the AOR in the SIP request and the subscription QoS information of the non-SIP service, it is determined whether the service feature information recorded by the service registry is the same as the AOR in the SIP request, and the SIP request is satisfied. The service characteristic information of the contracted QoS information, if any, obtains the actual access address and the corresponding service quality information from the service characteristic information that satisfies the condition. If the session initiation protocol request further carries the QoS information required by the non-SIP service, the specific process of the service registration center acquiring the QoS information and the actual access address corresponding to the non-SIP service according to the AOR in the SIP request includes the following steps:

Step A: The IMS queries the subscription service quality information of the non-SIP service from the home subscription server. Step B: Determine whether the service quality information required by the non-SIP service exceeds the subscription service quality information of the non-SIP service, and if not, according to the SIP request. The AOR and the service quality information required by the non-SIP service determine whether there is service characteristic information that satisfies the condition in the IMS, and if yes, acquire the actual access address and the corresponding service quality information in the service feature information satisfying the condition.

Step 106: The service registration center maps the parameters of the obtained quality of service information that need to be guaranteed by the network side into standard parameters, such as bandwidth, delay, jitter, and other application-independent standard parameters, and sends the SIP 18X response message to the application S-CSCF. Carrying the QoS information and an actual access address;

An example of the SIP response message is as follows:

SIP/2.0 18X

Via: SIP/2.0/UDP

192.168.1. l:10315;branch=z9hG4bK-d87543-3b51a73f7e3b5320-l-d87543-;rpor t=10315

</Parameter>

</service>

</AppQoS>

Step 107: The S-CSCF is applied to forward the SIP 18X response message to the calling S-CSCF. Step 108: The calling S-CSCF forwards the SIP 18X response message to the P-CSCF. Step 109: The P-CSCF will The standard parameters of the SIP 18X response that need to be guaranteed by the network side are parsed into QoS parameters that can be identified by the Policy and Charging Rules Function (PCRF), for example, the bandwidth is 60 Mbps, and is sent to the bandwidth. PCRF;

Step 110: The PCRF sends a resource reservation request to the gateway general-purpose wireless packet service support node (GGSN) according to the received QoS parameter.

Step 111: The GGSN reserves resources for the non-SIP service according to the resource reservation request sent by the PCRF.

Step 112: The GGSN returns a response message indicating that the resource reservation is successful to the P-CSCF.

Step 113: The P-CSCF forwards the SIP X18 response message to the service terminal, and carries the actual access address and the QoS information corresponding to the non-SIP service.

Step 113 can be performed in synchronization with step 109.

Step 114: The service registration center returns a SIP 200 success response message to the service terminal, and the service terminal returns a SIP Ack acknowledgement response message to the service registration center.

Step 115: The service terminal sends a request for accessing the non-SIP service according to the actual access address.

The GGSN uses the resources reserved on the GGSN to access non-SIP services.
